Thread: Toni Clarke fuel tank - how do they go together ?
29/09/2019 10:58:52

The fuel supply to carb goes on the cap . the other two nipples are a filler/drain and a breather and can be fitted in any suitable side of the tank. . No sealer should be required if parts are seated correctly ,just snug them up with correct spanner. Tip when you run the breather tube out of the model insert a piece of tube that is crimped with a pin in it . remove the pin and this will allow tank to breath but reduce any spills

yes + 1 for the DX7 . I'm not generally a Spectrum fan but do have a DX 7 for the Ready to fly small models available. The DX7 will work on DSM2 and DSMX and as already said will "model Match" . Model match is one thing I wish my FF9 had . Its also made by JR and feels a sturdy Tx. . Be careful of fake Spectrum rx on the market .

Good to see new parts fitted that makes a strong and light repair. Some repairs I've seen over the years can only be described as a flying epoxy brick .

Good work.

.... do people have a thing against mode 3 and 4? Can and does anyone fly these modes?

They do but are probably wired up wrong smiley,.........,joking. I did know a chap who flew a very odd mix and had elevator forward for up ? And throttle up to closed ? He crashed regularly . Keep it simple and do as your instructor does

If you are considering second hand then you can afford a Futaba or JR tx . A FF9 is a great tx and can be picked up for well under £100 as can the JR TXs . If you go for a 35 met set you can convert to 2.4 using FrSky module and Rxs.

Simple plug in conversion and very reliable, plus you can expand the model memory by pouting in a CamPac. Look for the later FF9 super easily identified by a red an blue led when switched on . The earlier model had a red and green led and is still a good TX . The "Super" has a few more features.

Its the main reaspon I dislike ARTF models. all clones of one another ! making your own colour scheme makes a model special . I was given a Cougar 2000 a year or so back . It had some damage so I stripped and recovered it giving it a totally different scheme. Its still just a Cougar but stands out head and shoulders above other cougars at the club

School children on strike over climate change !!!! How hypocritical is that ? Virtually all of them have to have a lift to school in the family Chelsea tractor and as already said , wouldn't they complain if they didn't have their holidays abroard . Little darlings don't you love them? The fault lies with the parents spoiling them . Am I being too hard ? may be a little but the University of life does that

Children have been duped/ used as a tool by climate change activists .

Let children walk or cycle to school as we did and that would be a start . Parents will argue its a different world now with more cars etc etc . Yes there are more cars because they are taking taking children to school ! Aren't the roads quiet during school holidays ?

Population explosion is the real threat . Food fight will be next , not the bun throwing type but real fights as food supplies become stretched .

Thread: ASP FS70 FRONT BEARING
24/09/2019 09:53:15
Posted by CARPERFECT on 23/09/2019 20:44:06:

Looking to replace the front bearing on my fs 70. is the bearing a sealed bearing ?

 

While your at it replace the rear bearing as well. Even tiny amounts of wear will change the valve timing enough to cause a drop in power. Rear bearing wear can be detected by holding prop atop and bottom an rocking back to front it,any play will be felt. Is it  a sealed or sheilded bearing ? Sheilded have a metal cover to prevent dirt from entering bearing while sealed have a rubber coated plate that is a actual seal on the rotating center of the bearing. Only the outer shield or seal is needed . Wash out grease and lubricate with appropriate oil before fitting.

Just replace like for like.

+1 for Simply Bearings.

Look up a local bearing factor as they also supply "o" rings and take the old ring to them for measuring . Failing that it's just luck trying the classifieds etc. I have been looking for a piston for the MDS 148 for months now but no luck but things like "O" rings and bearings are generic parts so you should be in luck.

Thread: Are all chargers unreliable?
19/09/2019 10:35:05

I just use Imax B6 off of E-Bay . Charge virtually any type of battery we use and lipos up to 6s .Cost around £13 each and last for years . Just had to replace one though after letting the smoke out after shorting it while being distracted !!!angry . Trouble with the multi channel chargers , if one channel blows then the whole lot is rubbish . The newer versions of the B6 have been improved to 80W from 50W

If you try the tap method ( not recommended ) make sure you screw the nut on the crankshaft to protect the thread.

Heat will release it but can often anneal the alloy if your not careful and get it too hot . The prop driver is then soft and can spread when used losing grip and come loose.

A puller is the only way to safely remove a tapered collet type prop driver. They can be very stubborn but quickly surrender to a puller. Pullers can be found on eBay for around £5 and don't take too long to arrive.

Bearings are available from many sources an Simply Bearing are IMO the best and quickest suppliers. Visit their website and it will show you how to measure the bearings . You will need a Vernier gauge . Model fixings may have the engine on their list so measuring the bearing will not be necessary .

Making gaskets is easy and my preferred material is thick brown envelope paper.

As I understand it, that is highly unlikely. All my planes have twin battery set ups, and i've never had an issue. wink

Hello Rich too.

That the trouble we never have an issue until we do however unlikely smiley. Some years ago twin battery set ups were virtually unheard of and considered by many as "over the top" . Fine until you experience a cell that goes open circuit then it all makes sense. Its worth the little extra time and effort if the model is a bit larger or expensive than your normal hack.

Over the years I have seen and experienced a lot of "The unexpected" occurrences that can often re-kit a model and battery problems from in-proper charging and neglect to new packs failing have featured heavily so a backer system is a simple and effective bit of protection JMO and each to their own .

I now make my own battery backer that cost just a few pence and are very simple, 

The Diodes will reduce the voltage very slightly up to 0.5 V .Also fit twin switches as these have bee known to wear and become erratic or un-reliable .

The battery backer in your link will do the same as a "Y" lead but will incorporate diodes to stop a faulty battery discharging through the good one as can happen with a normal "Y" lead. SM services sold a similar item some years ago but are no more .

The Glens Cap is nice plane to fly. Good luck .

Understood.

Not having got my Flycat yet, I don,t know if it will be noisy or not.

Good info on balancing. Thx.

Before removing the fan first try simply turning the adaptor and fan on the motor shaft a 1/4 turn at a time as this often cures the screaming out of balance noise.
